Answer:

  rectangle: 2x+2 wide by 2x high

  triangle: 2 high

Step-by-step explanation:

Usually, a problem like this is asking you to find dimension expressions that combine to give you the given expression. There are usually a number of possibilities. Using the designators in the attached, we would generally like to have B > C and A about the same as C. That doesn't seem possible with the given factors.

The given quadratic expression factors as ...

  area = 4x^2 +6x +2 = (2x+2)(2x +1)

This might be written to match the area formula as ...

  (2x +2)(2x +2/2)

This would give A=2, B=2x+2, C=2x, as shown in the attachment.
